[perl5.git] / Configure

#! /bin/sh
#
# If these # comments don't work, trim them. Don't worry about any other
# shell scripts, Configure will trim # comments from them for you.
#
# (If you are trying to port this package to a machine without sh,
# I would suggest you have a look at the prototypical config_h.SH file
# and edit it to reflect your system. Some packages may include samples
# of config.h for certain machines, so you might look for one of those.)
#
# Yes, you may rip this off to use in other distribution packages. This
# script belongs to the public domain and cannot be copyrighted.
#
# (Note: this Configure script was generated automatically. Rather than
# working with this copy of Configure, you may wish to get metaconfig.
# The dist-3.0 package (which contains metaconfig) was posted in
# comp.sources.misc and is available on CPAN under authors/id/RAM so
# you may fetch it yourself from your nearest archive site.)

ARGGGHHHH!!!!!

SCO csh still thinks true is false.  Write to SCO today and tell them that next
year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

(Actually, Configure ought to just patch csh in place.  Hmm.  Hmmmmm.  All
we'd have to do is go in and swap the && and || tokens, wherever they are.)

[End of diatribe. We now return you to your regularly scheduled programming...]

OOPS!  You naughty creature!  You didn't run Configure with sh!
I will attempt to remedy the situation by running sh for you...

stuck on a question, you may use a ! shell escape to start a subshell or
execute a command.  Many of the questions will have default answers in square
brackets; typing carriage return will give you the default.

On some of the questions which ask for file or directory names you are allowed
to use the ~name construct to specify the login directory belonging to "name",
even if you don't have a shell which knows about that.  Questions where this is
allowed will be marked "(~name ok)".

EOH
	rp=''
	dflt='Type carriage return to continue'
	. ./myread
	cat <<'EOH'

The prompter used in this script allows you to use shell variables and
backticks in your answers.  You may use $1, $2, etc...  to refer to the words
in the default answer, as if the default line was a set of arguments given to a
script shell.  This means you may also use $* to repeat the whole default line,
so you do not have to re-type everything to add something to the default.

Everytime there is a substitution, you will have to confirm.  If there is an
error (e.g. an unmatched backtick), the default answer will remain unchanged
and you will be prompted again.

If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
the questions and use the computed defaults (or the previous answers if there
was already a config.sh file). Type 'Configure -h' for a list of options.
You may also start interactively and then answer '& -d' at any prompt to turn
on the non-interactive behaviour for the remainder of the execution.

EOH
	. ./myread
	cat <<EOH

Much effort has been expended to ensure that this shell script will run on any
Unix system.  If despite that it blows up on yours, your best bet is to edit
Configure and run it again.  If you can't run Configure for some reason,
you'll have to generate a config.sh file by hand.  Whatever problems you
have, let me (perlbug@perl.org) know how I blew it.

This installation script affects things in two ways:

1) it may do direct variable substitutions on some of the files included
   in this kit.
2) it builds a config.h file for inclusion in C programs.  You may edit
   any of these files as the need arises after running this script.

If you make a mistake on a question, there is no easy way to back up to it
currently.  The easiest thing to do is to edit config.sh and rerun all the SH
files.  Configure will offer to let you do this before it runs the SH files.

Perl can be built to take advantage of threads on some systems.
To do so, Configure can be run with -Dusethreads.

Note that threading is a highly experimental feature, and
some known race conditions still remain.  If you choose to try
it, be very sure to not actually deploy it for production
purposes.  README.threads has more details, and is required
reading if you enable threads.

experimental.  This arrangement exists to help developers work out
which one is better.

*** WHOA THERE!!! ***

    Your gcc has not been compiled for the exact release of
    your operating system ($gccosandvers versus $osname$osvers).

    In general it is a good idea to keep gcc synchronized with
    the operating system because otherwise serious problems
    may ensue when trying to compile software, like Perl.

    I'm trying to be optimistic here, though, and will continue.
    If later during the configuration and build icky compilation
    problems appear (headerfile conflicts being the most common
    manifestation), I suggest reinstalling the gcc to match
    your operating system release.
